- eve get android's in-process unzip wrote every entry with default perms,
so gradle (and sdkmanager/aapt) came out non-executable on macOS
('Permission denied' during eve build android). Apply the unix mode from
the zip's external attributes (bits 16-23) on POSIX.
- consumer-test.sh launcher check: AAPT=find under set -o pipefail aborted
silently when build-tools was not under ANDROID_HOME; make it best-effort
(WARN instead of hard exit).
